Description

Technical Field

[0001] The utility model relates to the technical field of dredging devices, in particular to a device for cleaning mud and sewage. Background Technique

[0002] At present, engineering construction usually starts from the foundation pit to build the foundation. In areas with soft soil and heavy rainfall, it is easy to cause water accumulation in the foundation pit. After pumping, a large amount of mud and quicksand still remain in the drainage ditch, and it is difficult for manual labor to clean the mud completely, resulting in a dirty construction site.

[0003] For example, a Chinese utility model patent with the authorization announcement number CN204940178U and the authorization announcement date of January 6, 2016 discloses a silt treatment device, which specifically includes a wheelbarrow and a heavy object. A silt shoveling device is provided under the wheelbarrow. The silt shoveling device is provided with more than one fixed rod. The upper head of the fixed rod is fixedly connected to the wheelbarrow, and its lower head is connected to the shovel plate by bolts. The lower head of the fixed rod and the shovel plate are movably connected. More than one pull rod is provided at a position close to the front of the middle of the shovel plate. The pull rod is fixedly connected to the shovel plate and is connected to the wheelbarrow by bolts. The pull rod and the wheelbarrow are movably connected. The fixed rod and the pull rod form an angle between the shovel plate and the ground. During the process of shoveling silt, under the action of the forward thrust, the silt on the road surface can be cleaned through the shovel plate.

[0004] However, the existing silt treatment device can only shovel the silt from the ground, and it will still fall to the ground after passing through the shovel plate. Moreover, the fluid mud and quicksand will also scatter and flow away on the shovel plate, and the purpose of effectively collecting and cleaning the mud cannot be achieved. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the silt shoveled from the ground will still fall to the ground after passing through the shovel plate, and the fluid mud and quicksand will also scatter and flow away on the shovel plate, and the purpose of effectively collecting and cleaning the mud cannot be achieved.

[0006] In order to solve the above technical problems, the utility model provides a technical solution for a device for cleaning mud and sewage:

[0007] The device for cleaning mud and sewage includes a trolley, a mud guiding groove, an elastic scraper and a movable baffle. A sewage storage tank for collecting mud and quicksand is provided on the trolley, and the mud guiding groove is fixedly installed on the front side of the sewage storage tank;

[0008] An inlet for mud is provided at the end of the mud guiding groove far from the sewage storage tank. The elastic scraper is connected to the inlet for mud. An inlet channel for mud is formed between the elastic scraper and the mud guiding groove. The inlet channel extends along the front-back direction parallel to the trolley. During the mud scraping operation, the front edge of the elastic scraper is used for scraping and contacting the ground in a matching manner;

[0009] A sludge discharge port is provided at the end of the sludge guide trough close to the sewage storage tank, and the movable baffle is connected to the sludge discharge port. When the sludge is fed forward from the sludge guide trough to the sewage storage tank, the movable baffle conducts the sludge inlet passage; when discharging sludge in the reverse direction, the movable baffle closes the sludge inlet passage.

[0010] Further, the sludge guide trough is of a U-shaped trough structure. The sludge guide trough includes a bottom plate and two side plates fixedly connected to the edges of the bottom plate. The two side plates are arranged at intervals in the width direction of the trolley, and the bottom plate is fixedly connected to the upper edge of the sewage storage tank.

[0011] Further, the elastic scraper is a U-shaped scraper. The elastic scraper includes a bottom wall and two side walls fixedly connected to the edges of the bottom wall. The two side walls are arranged at intervals in the width direction of the trolley.

[0012] Further, the bottom wall is fixedly connected to the bottom plate, and the two side walls of the elastic scraper are in sliding fit with the two side plates of the sludge guide trough.

[0013] Further, a hinge shaft is provided above the sludge discharge port. The axis of the hinge shaft extends along the width direction of the trolley. The upper edge of the movable baffle is fixedly connected to the hinge shaft, and the movable baffle is in a blocking fit with the sludge discharge port in the closing direction.

[0014] Further, the sludge guide trough is an integral guide trough structure made of rigid iron sheet.

[0015] Further, the elastic scraper is an integral scraper made of elastic iron sheet.

[0016] Further, the trolley further includes wheels, a trolley handle and a support rod. The wheels are rotatably installed on the lower side of the sewage storage tank. The trolley handle is fixedly arranged at the rear side of the sewage storage tank, and the support rod is connected to the lower side of the trolley handle.

[0017] Compared with the prior art, the beneficial effects of a mud and sewage cleaning device of the present utility model are as follows: The mud and sewage cleaning device adopts a design form of a trolley, a sludge guide trough, an elastic scraper and a movable baffle. A sewage storage tank is provided on the trolley. The sludge guide trough is fixedly installed on the front side of the sewage storage tank. The elastic scraper is connected to the sludge inlet of the sludge guide trough; an inlet passage is formed between the elastic scraper and the sludge guide trough, and the inlet passage is arranged parallel to the front-rear direction of the trolley. When the trolley moves forward, there is a moving speed. Under the inertial action of the mud and quicksand, the mud and quicksand enter the sewage storage tank along the inlet passage.

[0018] During the cleaning work, the trolley is moved forward quickly, and the elastic scraper is used to scrape the mud and quicksand on the ground. The scraped mud and quicksand flow backward relative to the trolley through the mud guiding trough and enter the sewage storage tank through the mud discharge port. The mud guiding trough can prevent the fluid mud and quicksand from scattering and flowing away. Moreover, the elastic scraper can undergo elastic deformation, adapt to the unevenness of the ground, and fully fit and contact the ground, ultimately guiding and collecting the mud and quicksand in the sewage storage tank.

[0019] In addition, the movable baffle is connected to the mud discharge port. When the trolley moves forward, the movable baffle can not only conduct the mud inlet channel, allowing the mud and quicksand to enter the sewage storage tank from the mud guiding trough in the forward direction; moreover, when the trolley decelerates, the mud and quicksand in the sewage storage tank can flow back to the mud discharge port. At this time, the movable baffle can automatically close the mud inlet channel to block the reverse discharge of the mud and quicksand, preventing the mud and sewage in the sewage storage tank from possibly falling to the ground and ensuring the effective collection and cleaning of the mud.

[0029] As Figures 1 to 4 shown, a mud and sewage cleaning device according to an embodiment of the present utility model includes a trolley 1, a mud guide groove 2, an elastic scraper 3, and a movable baffle 4. A sewage storage tank 10 for collecting mud and quicksand is provided on the trolley 1, and the mud guide groove 2 is fixedly installed on the front side of the sewage storage tank 10; a mud inlet 21 is provided at the end of the mud guide groove 2 away from the sewage storage tank 10, and the elastic scraper 3 is connected to the mud inlet 21. An inlet mud passage 20 is formed between the elastic scraper 3 and the mud guide groove 2, and the inlet mud passage 20 extends along the front-rear direction parallel to the trolley 1.

[0030] During the mud scraping operation, the front edge of the elastic scraper 3 is used for scraping and contacting the ground in cooperation; a mud outlet 22 is provided at the end of the mud guide groove 2 close to the sewage storage tank 10, and the movable baffle 4 is connected to the mud outlet 22. When the mud flows forward from the mud guide groove 2 to the sewage storage tank 10, the movable baffle 4 conducts the inlet mud passage 20; when the mud flows out in the reverse direction, the movable baffle 4 closes the inlet mud passage 20.

[0031] The mud and sewage cleaning device adopts a design form of a trolley 1, a mud guiding groove 2, an elastic scraping plate 3 and a movable baffle 4. A sewage storage tank 10 is provided on the trolley 1. The mud guiding groove 2 is fixedly installed on the front side of the sewage storage tank 10. The elastic scraping plate 3 is connected to the mud inlet 21 of the mud guiding groove 2. An inlet mud channel 20 is formed between the elastic scraping plate 3 and the mud guiding groove 2, and the inlet mud channel 20 is arranged parallel to the front-back direction of the trolley 1. When the trolley 1 moves forward, it has a moving speed. Under the inertial action of the mud and quicksand, the mud and quicksand enter the sewage storage tank 10 along the inlet mud channel 20.

[0032] During the cleaning work, the trolley 1 is moved forward quickly. The elastic scraping plate 3 scrapes the mud and quicksand on the ground. The shoveled mud and quicksand flow backward relative to the trolley 1 through the mud guiding groove 2 and enter the sewage storage tank 10 through the mud discharge port 22. The mud guiding groove 2 can prevent the fluid mud and quicksand from scattering and flowing away. Moreover, the elastic scraping plate 3 can undergo elastic deformation, can adapt to the uneven ground and fully fit and contact the ground, and finally guide and collect the mud and quicksand in the sewage storage tank 10.

[0033] In addition, the movable baffle 4 is connected to the mud discharge port 22. When the trolley 1 moves forward, the movable baffle 4 can not only conduct the inlet mud channel 20, allowing the mud and quicksand to enter the sewage storage tank 10 from the mud guiding groove 2 in the forward direction for mud inlet; moreover, when the trolley 1 decelerates, the mud and quicksand in the sewage storage tank 10 can flow back to the mud discharge port 22. At this time, the movable baffle 4 can automatically close the inlet mud channel 20 to block the reverse mud discharge of the mud and quicksand, avoiding the possible falling of the mud and sewage in the sewage storage tank 10 to the ground and ensuring the effective collection and cleaning of the mud.

[0034] In this embodiment, the mud guiding groove 2 is of a U-shaped groove structure. The mud guiding groove 2 includes a bottom plate 23 and two side plates 24 fixedly connected to the edges of the bottom plate 23. The two side plates 24 are arranged at intervals in the width direction of the trolley 1. The bottom plate 23 is fixedly connected to the upper edge of the sewage storage tank 10. The two side plates 24 of the mud guiding groove 2 can play a role in side blocking, preventing the mud and quicksand from scattering and flowing away outward, and ensuring the reliability of collecting the mud and sewage.

[0035] Correspondingly, the elastic scraping plate 3 is a U-shaped scraping plate. The elastic scraping plate 3 includes a bottom wall 31 and two side walls 32 fixedly connected to the edges of the bottom wall 31. The two side walls 32 are arranged at intervals in the width direction of the trolley 1. The two side walls 32 of the elastic scraping plate 3 can prevent the shoveled mud and quicksand from flowing away outward, ensuring that the mud and sewage can be guided into the mud guiding groove 2.

[0036] Moreover, the bottom wall 31 is fixedly connected to the bottom plate 23, and the two side walls 32 of the elastic scraper 3 are in sliding fit with the two side plates 24 of the mud guide groove 2. During the cleaning operation, the front edge of the elastic scraper 3 contacts the ground by scraping, causing the bottom wall 31 to undergo elastic bending deformation. At this time, the two side walls 32 of the elastic scraper 3 slide relative to the mud guide groove 2, meeting the requirement of the elastic bottom wall 31 for self-adaptive bending deformation during scraping.

[0037] As a further preferred solution, a hinge shaft 40 is provided above the mud discharge port 22. The axis of the hinge shaft 40 extends along the width direction of the trolley 1. The upper edge of the movable baffle 4 is fixedly connected to the hinge shaft 40, and the movable baffle 4 and the mud discharge port 22 are in a blocking fit in the closing direction. The movable baffle 4 is hinged to the mud discharge port 22. Under the action of its own weight, the movable baffle 4 can maintain the state of closing the mud inlet channel 20. During the cleaning operation, the impact force of the incoming mud can smoothly push open the movable baffle 4. On the contrary, it can prevent the mud and quicksand in the sewage storage tank 10 from flowing back, achieving the purpose of forward conduction of incoming mud and reverse blocking of outgoing mud.

[0038] Specifically, the mud guide groove 2 is an integral guide groove structure made of rigid iron sheet, and the elastic scraper 3 is an integral scraper made of elastic iron sheet. The rigid iron sheet can be made into the mud guide groove 2 by bending process, and the elastic iron sheet can be made into the elastic scraper 3. The processing difficulty and cost are low, meeting the structural requirements of elastic scraping and rigid support.

[0039] In addition, the trolley 1 further includes wheels 11, a trolley handle 12 and a support rod 13. The wheels 11 are rotatably installed on the lower side of the sewage storage tank 10. The trolley handle 12 is fixedly arranged at the rear side of the sewage storage tank 10, and the support rod 13 is connected to the lower side of the trolley handle 12. The worker pushes the trolley 1 forward using the trolley handle 12, adjusting the trolley 1 to tilt forward and downward to ensure that the elastic scraper 3 can effectively scrape and contact the ground. After the collection is completed, the trolley 1 is placed flat on the ground and supported by the support rod 13 to ensure that the entire trolley 1 remains upright.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
